摘要
最近发展了一种数值技术，通过矩量法处理任意形状的印刷电路天线(见H. Nakano et al. 1987)。然而，这种数值方法的缺点是，当采用矩量法时，缺乏对阻抗矩阵元素的有效计算。结果表明，采用C.L. Chi(1987)的图像提取方法可以显著提高计算效率。分析是基于动态格林函数的分解。这种有效的数值技术的应用之一是研究印刷螺旋天线的辐射特性。以半椭圆结构的印刷螺旋天线为算例。
On the modeling of arbitrarily-shaped printed circuit antennas
A numerical technique has recently been developed to deal with printed circuit antennas with arbitrary shapes via the method of moments (see H. Nakano et al. 1987). However, the drawback of this numerical approach is the lack of efficient evaluation of impedance matrix elements when the moment method is enforced. It is shown that the image extraction method of C.L. Chi (1987) can be used to enhance the computation efficiency significantly. The analysis is based on the decomposition of the dynamic Green's function. One of the applications of this efficient numerical technique is to study the radiation characteristics of a printed spiral antenna. A printed spiral antenna composed of semi-ellipses is considered as a numerical example.<>
